Anti-LSM5 antibodies are used in the immunodetection of the protein LSM5 homolog, U6 small nuclear RNA and mRNA degradation associated. In humans, the canonical protein has a reported length of 91 amino acid residues and a mass of 9.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. A member of the SnRNP Sm proteins protein family, LSM5 is known to play a role in pre-mRNA splicing as component of the U4/U6-U5 tri-snRNP complex that is involved in spliceosome assembly, and as component of the precatalytic spliceosome (spliceosome B complex). Synonyms for this target antigen include U6 snRNA-associated Sm-like protein LSm5, LSM5 U6 small nuclear RNA and mRNA degradation associated, LSM5 homolog, U6 small nuclear RNA associated, and YER146W. LSM5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the LSM5 antibodies listed below. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
